Spraying Apple Orchakds in a Wet Season. 365 



and directed the spray ^'hile the other pumped. The nozzle nsed 

 was one invented "by the owner of the orchard. It throw« a line 

 fepray with much force, which makes it well adapted for orchard 

 work. 



The amount of liquid applied to each tree averajj^ed about four 

 and one-half gallons pei* application. The trees are about twenty 

 years old. They are thrifty and in excellent condition. The 

 retail price of the ^sulphate of co^yper is about eight cents ])er 

 pound, and Paris gi'een is sold for about tihirty-fi \e cents. Adding 

 the cost of the lime at thirty cents i>er bushel, this makes the 

 actual outlay per ti'ee for material about' five cents for each applicii- 

 tion of the combination of Bordeaux mixture and l*aris green. If 

 Ijondon purple wei'e used it would reduce the cost a little for this 

 poison should sell for about twenty cents a pound retail. If Paris 

 git'en is used alone the cost of each api)lica.tion is lesis than oiu' 

 cent per tree. Two men should spray frmn 100 tb 125 trees })ei 

 day and do the work well. Counting the c<jst of applying at two 

 cents per tree, this makes the total cost of each application of the 

 combined insecticides and fungicides seven cents per tree, or about 

 twenty-five cents for four applications, this number being perhaps 

 suflflcient in even veiy wet seasons. 



Most of the petals fell from the trees June sixth and seventh. 

 The first application was made June thirteenth, the weather in 

 the meantime being warm and damp. This application was with- 

 ani doubt delayed too long, for at the time of the second applica- 

 tion, June twenty-secoiid, diseased spotis could be found both aiH)n 

 the young fruits and ujKtn the leaves in some of the places which 

 were thickly covered with the Bordeaux mixture, thus sliowiiig 

 that the work of the fungus began very early in the seasfm. Tlie 

 firsit application should be made at the latest, immerliately afttT 

 the blossoms fall, and it is probable that good results will follow one 

 made earlier. 



The orchard was sprayed a thii'd time July first, and again July 

 twenty-second, the mixture in each case being jirepared as for the 

 first application. 



The apples were harvested etirly in October and at that rime 

 they were carefully examined with regard to the amount of scab
